I am trying to retrieve selected values of multivalued picklist from the Salesforce record and mapping them into a dropdown list of a LWC component. In order to retrieve, I have used wire adapters as below.

So far I can retrieve the prepopulated values on the salesforce records as semicolon separated values. eg:45;78;80. What I need is seperating those values and show them as dropdown values in my lwc component

 import {
} from 'lwc';
import {
} from 'lightning/uiObjectInfoApi';
import {
} from 'lightning/uiRecordApi';
import COURSE_ORDER1_OBJECT from '@salesforce/schema/Course_Order__c';
import CREDIT_VALUES from '@salesforce/schema/Course_Order__c.Organization__r.Credit_Value__c';


export default class lwcAssociations extends LightningElement {
    @api title = "LWC Association"
    @api credit_values = "Credit Value";
    @api button = "FINISH";

    @api recordId;
    @track value;
    @track credit_val_list=[];


    @wire(getPicklistValues, { recordTypeId: '$objectInfo.data.defaultRecordTypeId', fieldApiName: CREDIT_VALUES})

    get creditValues(){
        return getFieldValue(this.record.data,CREDIT_VALUES);

    handleChange(event) {
        this.value = event.detail.value;

        var credit_values = this.creditValues;
        this.credit_val_list = credit_values.split(',').map((fld) => fld.trim());


Can someone help me splitting these values seperated by semiclons and map them into the picklist field in the template?


    <div style="margin:20px; margin-bottom:150px; ">

                <header class="slds-modal__header">
                    <h6 id="modal-heading-06" class="slds-text-heading_medium slds-hyphenate"><b>{title}</b></h6>
                <br />
                <!-- 1st row -->

                    <div class="oneline">
                        <template if:true={credit_val_list}>

                            <lightning-combobox label={creditValues} name="creditValue" value={value} options={credit_val_list}




lightning-combobox does not support multiselect. You'll have to use lightning-dual-listbox

Also, the correct way to pass options to a lightning-combobox or lightning-dual-listbox is to pass list of objects with value and label property.

Markup -

<lightning-dual-listbox options={options}></lightning-dual-listbox>

JS -

 export default class LwcAssociations extends LightningElement {

    options = [
        { label: 'English', value: 'en' },
        { label: 'German', value: 'de' },
        { label: 'Spanish', value: 'es' }

  • I am retrieving multipicklist values from salesforce record using wire adapters and just wanna display them in a dropdown. Actually want to map the retrieved data into dropdown – Ruklani Attanyake Jan 18 at 12:02
  • What will be the return value of wire adapter? A comma separated values? – Jay Rathod Jan 18 at 12:06
  • semi colon seperated values – Ruklani Attanyake Jan 18 at 12:08
  • Ok, help me understand. So, is it something like, you need to display a multiselect picklist field with values prepopulated based on a record's values? – Jay Rathod Jan 18 at 12:10
  • You are correct. Those prepopulated values can be retrieved by wire adapter with the help of get credit2Values() as values seperated by semicolons. Eg: 45;78;65. These returns values are just prepopulated on the salesforce record. So what I need is showing those values on the combo box as dropdown values in my lwc component. – Ruklani Attanyake Jan 18 at 12:16

I updated the get creditValues() as follows. After splitting the String seperated by commas, I pushed the resulting array into a new array.

 get creditValues() {
        var credit;
        var credit_val_list = [];
        credit = getFieldValue(this.record.data, CREDIT_VALUES);
        credit_val_list = String(abcd).split(";");
        console.log("Credit val" + credit_val_list);

        var i;
        var options = [];
        for (i = 0; i < credit_val_list.length; i++) {
            var item = {
                label: credit_val_list[i],
                value: credit_val_list[i]

        return options;
